## Questions & Answers

**Q: Can this be cut to two inch width?**
A: Yes. It has a backing on it that you pull off before you stick it down.  You could cut it before you take the backing off.  But make sure you do it before, since it is really sticky once the backing is off.

### ⭐⭐⭐⭐⭐ Review
*by E***K on 27 March 2026*

Las cintas hechas en US son infinitamente superiores a cualquier version o imitacion china. Es verdad, pagas más, pero la relacion beneficio/costo superar de lejos a las copias chinas. La recomiendo esta marca, junto con la del dinosaurio y la del primate. Es una muy buena opcion cuando vives fuera de US y no puedes comprar las otras 2 mencionadas.
